Ok, so i went down to charleston this weekend to party at my buddies place, 20k acres of nice trails right along the black river, and on the way down i heard something pop in my axle or brake(i'm not sure which). It is the rear passenger wheel and i could feel it tugging and clanking so i pulled over. I checked it out and didnt really see anything(it was at night) so i just kept driving it to my buddies place and just hoped it arrived intact. On the way i sprayed some wd-40 on it thinking it might be a small rock that jumped up into the rotor or something. So when i get to my buddies place and put a light to it, the rotor had been grinded quite a bit and it was leaking some kind of fluid, and alot of it. I let it sit there for about 2 hours and there was about a 1 ft. puddle that had dribbled down from the axle/brake. It was a very dark, but thinish texture. Does anyone have any ideas?
